CO2 capture by means of chemical looping combustion

Pavone, D.
IFP, Lyon, Vernaison, France

In a search of concepts for innovative reactors allowing CO2 capture in gas turbine, monolith based chemical looping combustion has been identified as a promising concept. A precise simulation of the chemical looping combustion in a channel of monolith is developed to define the design rules and the material specifications. The objective is also to evaluate this innovative process in terms of power yield and CO2 capture efficiency.

To build the simulator with few efforts and to keep enhancement possibilities, we choose COMSOL Multiphysics (FEMLAB 3.1). The simulator of the chemical looping combustion is presented, its main assumptions and some numerical difficulties and how they have been solved. Then some numerical results are given derived from a numerical demo, for illustration.
